The utility model provides a technical scheme that its technical problem adopted is: a centre comprises a centre head and a centre body, wherein the centre head is a hollow cone, the hollow structure is a quadrangular pyramid, the conical surface of the centre head is provided with four identical V-shaped grooves which are gradually deepened from top to bottom, and the included angle of the V-shaped grooves is 150 degrees; the center body comprises a connecting part, a transition part and a center handle part, and the connecting part is a rectangular pyramid matched with the rectangular pyramid-shaped hollow structure of the center head; the transition part is a cylinder, and a transition recess is arranged on the cylinder corresponding to the V-shaped groove of the top pointed end; the handle part of the centre is a tapered cylinder and is formed by connecting a small cylinder at the bottom, and the cross section of the centre is in an axisymmetric pattern of an isosceles trapezoid with a small rectangle; the surface of the joint of the transition part and the tip handle part is provided with a spiral groove.
The utility model provides another kind of technical scheme that its technical problem adopted is: a centre comprises a centre head and a centre body, wherein the centre head is a hollow cone, the hollow structure is a quadrangular pyramid, the conical surface of the centre head is provided with four identical V-shaped grooves which are gradually deepened from top to bottom, and the included angle of the V-shaped grooves is 150 degrees; the center body comprises a connecting part, a transition part and a center handle part, and the connecting part is a rectangular pyramid matched with the rectangular pyramid-shaped hollow structure of the center head; the transition part is a square, and the side length of the square is less than the connecting line length of bottom points of two opposite V-shaped grooves of the tip body; the handle part of the centre is a tapered cylinder and is formed by connecting a small cylinder at the bottom, and the cross section of the centre presents an axisymmetric figure with a small rectangle on an isosceles trapezoid.
The transition part is provided with a recess so as to facilitate the tool withdrawal during use, and the transition part is arranged into a square cylinder to facilitate the assembly and disassembly.
The center point head and the center point body are made of two different materials and are connected through brazing welding.
The beneficial effects of the utility model are that fixed top has the function of heavy load rough machining, high-speed processing and finish machining and super finishing, and top possesses from the function of revising, self-lubricating, automatically cleaning and self-compensation, can reduce top service condition, accomplishes characteristics safe and reliable, that the incorruptibility is high, longe-lived.
